I wondered if this was something that applied to all types of adverts on VS but it seems to only be used in the Free Personals and adult services section.
I think this is showing us that there are people who are setting up adverts for WGs on VS as part of some sort of arrangement they have with those service providers.
Call them agencies, fixers, handlers, managers, secretaries, or other words of your choice.
It doesn't mean the advert for a particular WG is suss, but there have been examples of people setting up dozens of adverts, using the same images, for different locations across the UK, at the same time, which is obviously suspicious.
I am generally a bit more confident if there's just one advert linked to a profile, but, as with many things, it's not a guarantee that advert is going to be genuine.
I just found one profile with 7 adverts, with identical wording for each one, and only 2 with images, which does make me more suspicious, and another profile with 5 adverts for same area, comprising 2 Filipinos, a TS, and 2 Brazilians, so certainly looks like an manager set up the adverts, maybe all associated with same location.
